Jerky throttle

[brazae]

Anyone else experience 'jerky throttle syndorome' Seem to have an off/on sort of attitude happening particularly when filterning in 1st and 2nd gears (which I currently do a lot of).

Have come from a history of silky in-line fours so might be a bit of aclimatisation but it definately feels wrong. Test rode an Aprilia Pegaso and they had problems with the Throttle Position Sensor, wondering if its the same sort of thing here? My old FZ6 Fazer had a similar problem due to fuelling which was helped by new cans and a K&N filter. Do these help on the F800GS in the same way?

Thanks

They are all like that mate, some say fitting a 15 tooth front sproket helps, it seemed to help a bit on mine, and it pulls harder

The Fazer first, it is was fueled by a carbie (problem fixed by mods) it was most likely being over fuel. Thus mods kept the fuel same, increased the air and gave you better performance and economy.
In-line fours, the develop more power but less(later) torque. Twins and singles develop torque lower in the rev range, which is better for the slower speeds of offroading.
School, power= ability to go fast, produced by rapid application of force. Torque= ability to push a heavy weight, produced by big bangs and long strokes/pushes.

So, the torque maybe a cause, EFI will take care of the fuel issue so it is not that. But the most likely cause is the nut that connects the handle bars to the seat. (No criticism, just a funny quote that I saw someone else use on this site).

You do get used to the throttle but it will never be 100% smooth even with practice. Becomes more of a challenge off-road where slipping the clutch will help somewhat.

The bike responds to being ridden aggressively, which can be a liability off road, but you do learn how to use it, and the clutch a little more.

There was a software update to improve the response I believe.

I find myself having to use the clutch a lot when adjusting low end speed in gears 1, 2 and maybe 3, this usually solves the problem for me.

Too add, many people original were disppointed with the fact the the 800gs (the adventure model) did not come with a lower 1st gear. This originally didn't phased as I did not take my bike medium off road. Since then I understand their argument, but I have also discovered since that uphill keep the power on and don't loose momentum, otherwise you are stuffed.
